Fruit data were collected from photocopies of herbarium specimens (A.G. Voorhoeve 68 and Service de la Côte d'Ivoire 2812), and the seed data from a photograph of two seeds.
Tribe Detarieae
Bruneau et al. (2000) carried out extensive phylogenetic analyses of tribes Amherstieae and Detarieae. They concluded that they form a single monophyletic group. Therefore, they supported Polhill's (1995a, 1995b) decision to unite the two tribes.
